"We must also accept the possibility of Gestalt qualities comprehending complexes of elements of different categories."

“Is it not conceivable, that each tone is the fusion of a sum of still more primitive elements with the Gestalt qualities bound up therewith?... No conclusive argument can be brought forward even against the possibility that we may not, penetrating ever more deeply in this manner, finally arrive at a single proto-quality, or at least at a single quality-continuum, from out of which distinct contents are generated by the fusion of distinct combinations with the Gestalt qualities bound up therewith, one can no longer shrink from the idea that tones and colours might be exhibited as the products of a much higher degree of complication of proto-elements as yet unknown.”

“It will first of all be clear that not only incompatible but also compatible characters can be thought in emptily intended combinations. This indeed takes place very often, as a result of that parsimony which nature always brings to bear in the achievement of her aims. Unintuitive presentation demands much less expenditure of effort than the intuitive, and thereby goes proxy for the latter in very many cases. Thus anyone confronted with, say, a complicated description of a work of architecture will first of all form a merely indirect presentation of it, which will then be rounded out by gradual execution or fulfilment of the various merely intended components, to yield an intuitive total picture.”

“Not all desired things are valuable, but rather only those which are worthy of being desired. Whether this worthiness belongs to a thing, however, is not in the particular case yielded from the investigation of the objective nature of the thing, but rather from the subjective consideration of the desire directed at the thing. From the examination of our own mental activity in the act of desire we discern whether this is directed at something valuable or not.”

“For the intimate fusion of touch, temperature and sometimes also taste and smell sensations into a single unified total impression raises the question of whether we do not have here Gestalt qualities which are built up upon a foundation belonging to several sensory regions. As can easily be recognized, it is just as possible that a complex of, say, touch and temperature sensations should provide the foundation for a Gestalt quality as should a complex of sound sensations. Indeed no a priori objection can be raised even against the idea that there should exist sound-colour-Gestalten spanning the data of the senses of sound and vision as something like a bridge - even though we do not believe that we can detect anything of this sort in sensation.”

“By a Gestalt quality we understand a positive content of presentation bound up in consciousness with the presence of complexes of mutually separable elements. That complex of presentations which is necessary for the existence of a given Gestalt quality we call the foundation of that quality.”
